Britney has a genetic birth difference (not defect – her parents don’t consider her defective at all) called Achondroplasia. Achondroplasia is the most common form of Dwarfism. Ok terms to use are: dwarf, little person, or short-statured. (The term “midget” is considered highly offensive to dwarfs). We are lifetime members of the national organization founded in 1959 by Billy Barty for people of short stature called Little People of America. Little People of America (LPA) also has a local chapter in Arizona that we belong to called the Valley of the Sun Chapter (or AZlpa for short).
